# Reference design for ad834 is not working in multisim

I just only make model for RMS-to-DC converter based on http://www.analog.com/media/en/technical-documentation/application-notes/AN-212.pdf .I have tested, i think, that schematic is correct, but output always 0 V. Whats the problem ?

• I use Multisim 14.0. Model for ad834 was taken from multisim library. The only one thing i have done is some tests with builted model. As i understood is that ad834 is used to make a multiplication { (X-0)*(X-0)=X^2) , capacitors and resistors are used to take integral (in other words get the average) and than  takes root. The model for sine wave +1 V should have on the out ~0.71 V
